Reports from some users on Lenovo Forums say that their laptop is BIOS locked to "RAID" storage mode again and that installing Linux to their SSD is a no-go.
Do I expect to have any such problems on the Legion Y520?
I will majorly using linux (Probably Ubuntu Mate) for development purposes.

Before I buy a Lenova, I’m wondering if other users experienced trouble installing Ubuntu Linux on the Legion Y520. I couldn't find any experience with Linux and this machine at all. For me, it's not necessary to run a Windows-Linux dual boot situation. Just Linux is fine. The question is whether Ubuntu supports all hardware properly or not.
Hope to hear soon from you,
a candidate Lenovo owner

I have been using Ubuntu/Win10 dual boot for a while and so far everything is good. The RAID configuration can be switched to AHCI in BIOS, and all hardware seem to work just fine. Nvidia GTX 1050 Ti driver installs as expected in both Ubuntu and windows.
Here is a few tweaks needed:
(1) wifi card hard block can be fixed with a single command:
(2) UTC/local time tweak for dual boot

I got the machine a day ago and just set up Ubuntu MATE dual booted with the pre-loaded Windows 10. It's working quite well now. But I did experience some problems setting it up.
1. Had to change to AHCI mode in BIOS, default was Intel RST. Or else Ubuntu installation was not detecting the hard drives.
2. WiFi and Bluetooth were Hard-Blocked for Ubuntu MATE. Had to install using Ethernet.
> Once installed, when it booted up, WiFi and Bluetooth were still Hard-Blocked.
Fix: Added `blacklist ideapad_laptop` at the end of the file "/etc/modprobe.d/blacklist.conf" and reboot.
3. After Ubuntu MATE was set up, when I tried booting up windows, Windows MBR wasn't able to find the drives and threw a Blue Screen of Death.
Fix: Enter Safe Mode in windows from Recovery settings/Advanced Options and wait for 5 mins or so... Reboot. And done, Windows is working.
Currently the system is working as it should, no problemo
Thanks to sahfdoiwa, He already answered many questions.

I have installed dual boot W10 + Ubuntu 16.04.3 LTS in my Legion Y520
Everything went ok in the installation. Only problem was the wifi card "hard block" issue , apparently solved following the instructions of the link shared before (https://askubuntu.com/questions/893384/wifi-doesnt-work-on-fresh-ubuntu-16-04)
The main problem that I am facing now is that wifi network seems to fail after 5 or 10 minutes using it. I start to see problems while using firefox, and after this a get a message in the screen, saying that WIFI connection is OFF
If I reboot the computer, the the cycle begins again...
Did you have the same experience? did you find a solution?
Thank you all!

I have the same problem than MrJL on my Lenovo Y520 on Linux Mint Cinnamon 18.2 : the wifi disconnects after a random period, and a restart fix it before it happends again... I have no problem through ethernet. Any idea?

Thanks! This reminds me to my efforts to dual boot Win7 next to Ubuntu on my HP Envy notebook. Windows had the dominant policy to claim the PC just for itself. (common UEFI-issue?) I ended up erasing Windows entirely. Now Ubuntu runs smooth & peacefully alone.
B.T.W. Are there more arguments for you guys to buy a Lenovo, except the interesting price?

Per your comments as well as sahfdoiwa's, and also previous experiences attempting to install Linux OSs alongside Windows 10 over UEFI, I wonder whether you guys actually had to fall back to a legacy bios based set-up. Or you actually acomplished to have both OS with dual-boot over UEFI (without spoiling the pre-existing Windows 10 system)?
I have a Y520 with a main SSD drive (where W10 comes pre-installed) + 1 TB HDD, I guess your case is similar. I want to dual-boot from the SSD maintaining the W10 usable mostly for gaming.
In the case the dual-boot was accomplished over UEFI, would you please confirm the next items:
- On the UEFI, did you switch from RAID mode to AHCI/SATA mode?
- Did you disable fast boot in UEFI Settings and disabled fast starting in Windows preferences?
- Have you partitioned the SSD disk after booting-up the linux installation media? of did you use a tool like gparted to partion the SSD before hand?
